Hey everyone!
I made some little updates on Yaru to better support Unity with PR https://github.com/ubuntu/yaru/pull/1670 now in master (together with PR 1671), and I’d love if anybody can give it a try and report some feedback.
There are some problems, but I don’t think they can be fixed on Yaru side, as example some applications have a titlebar together with the headerbar (Nautilus, Gnome Software) and other don’t (settings). Since headerbars have a top light border, this is quite visible, but to avoid it I should make a build specifically for Unity, which is not possible at the moment.
EDIT: I just saw the problem with headerbar is discussed here
